I have a 1994 F150 XLT 5.0 . The problem i am having is when I turn the ignition on I hear the fuel pump come on [both front and rear tanks] and it should stop when the system is pressurized but it does not,and the truck then fails to start.Intermittantly the pump does stop and the truck starts up
There is fuel at the rail and there is spark,i have changed the filter ,fuel pressure regulater and the pump relay to no avail.
So if any one has any ideas it would be greatly appreciated.
You have a bad computer with a non running clock.
You have bad electrolytic capacitors in the computer.
When the clock starts then the fuel pump will quit after one second run time and the engine will start.
Pressure has nothing to do with with this problem.
I do not think you can buy a new one.
You can get a rebuilt one from most auto part stores and some online stores or a used one from a salvage yard or on ebay.
Some also replace the electrolytic capacitors in the computer themselves or have radio/TV repair shop do it.
There are also some place in Florida that you can send them to that will repair it for you.
